Unable to see some gallery items.

I am on PS5 and have noticed that the gallery filters out content marked as using CC.

I upload paintings and photographs by my Sim to the gallery. Some people have told me that these mark as CC,  but they don’t for me.

However, I have noticed today that I cannot see some of my gallery items anymore,  and I wonder if they have been marked as using CC. I would like this resolved so that I can access these gallery items again.
